Question on struct

Write a struct called Song. Song will have the data members string title, string artist, int yearRecorded, string genre, int lengthMin, and int lengthSec. This struct will have object-values song1, song2, song3, song4, song5, song6, song7 and song8.

Add your code for the struct Song to the following code. Then test that it runs, what exactly is printed when it is run?

void printSong(Song);

int main() {
song1.title = "YYZ";
song1.artist = "Rush";

song1.yearRecorded = 1981;
song1.genre = "rock";
song1.lengthMin = 4;
song1.lengthSec = 25;
printSong(song1);
return 0;
}

void printSong(Song s) {
cout << s.title <<
       " By " << s.artist <<
       " (" << s.yearRecorded << ")" <<
       " [" << s.genre << "]" <<
       " {" << s.lengthMin << ((s.lengthSec < 10) ? ":0" : ":") << s.lengthSec << "} " << endl;
}

Create song2, song3, song4, song5, song6, song7, and song8 to be your choice of songs in the code. Test your code using the function printSong(Song) to print each of them. Show what is printed by your code.

Add the following code to your program. Insert this struct below the struct Song, but above your function prototypes. Make sure your code compiles and can be run.

struct MixTape {
string title;
Song track1;
Song track2;
Song track3;
Song track4;
Song track5;
Song track6;
Song track7;
Song track8;
int totalLengthMin;
int totalLengthSec;
} myMixTape;

Modify your main method by defining myMixTape so that its title is “My Mix Tape”, its Song members are song1 through song8, and its totalLengthMin and totalLengthSec are the sum of the lengthMin and lengthSec of all its Song members. (THINGS TO REMEMBER: when adding up the minutes and seconds of tracks, how many seconds do we add up in order to add one minute?)

Modify your code by adding a function declared like void printMixTape(MixTape); That prints the MixTape parameter by printing the title, totalLengthMin, totalLengthSec, and each of its tracks. Test your code by using this method in your main.

EXTRA CREDIT: modify the struct MixTape and all other necessary code so that MixTape has an array of Songs called tracks of size 8 rather than 8 individual Songs. Test your code by running it with your printMixTape method on your new MixTape struct.

Answer 1

Answer #1

a)

Code:

#include <iostream>
using namespace std;
struct Song{
string title;
string artist;
int yearRecorded;
string genre;
int lengthMin;
int lengthSec;
};
int main(){
Song song1,song2,song3,song4,song5,song6,song7,song8;
return 0;
}

Code screenshot:

Output (Since it is just the declaration of objects,so the output is blank as shown below):

b) Code after integrating the test code:

#include <iostream>
using namespace std;
struct Song{
string title;
string artist;
int yearRecorded;
string genre;
int lengthMin;
int lengthSec;
};
void printSong(Song);
int main(){
Song song1,song2,song3,song4,song5,song6,song7,song8;
song1.title = "YYZ";
song1.artist = "Rush";
song1.yearRecorded = 1981;
song1.genre = "rock";
song1.lengthMin = 4;
song1.lengthSec = 25;
printSong(song1);
return 0;
}
void printSong(Song s) {
cout << s.title <<
" By " << s.artist <<
" (" << s.yearRecorded << ")" <<
" [" << s.genre << "]" <<
" {" << s.lengthMin << ((s.lengthSec < 10) ? ":0" : ":") << s.lengthSec << "} " << endl;
}

Code (just added the new MixTape Structure with rest of the code remain same as demanded in the question):

#include <iostream>
using namespace std;
struct Song{
string title;
string artist;
int yearRecorded;
string genre;
int lengthMin;
int lengthSec;
};
struct MixTape {
string title;
Song track1;
Song track2;
Song track3;
Song track4;
Song track5;
Song track6;
Song track7;
Song track8;
int totalLengthMin;
int totalLengthSec;
} myMixTape;
void printSong(Song);
int main(){
Song song1,song2,song3,song4,song5,song6,song7,song8;
song1.title = "YYZ";
song1.artist = "Rush";
song1.yearRecorded = 1981;
song1.genre = "rock";
song1.lengthMin = 4;
song1.lengthSec = 25;
